Yeah both came from the top edge of a hydraulic sluicing area...old glass around, no chimney, and I think half of the flat spot was washed away....so maby from an earlier camp before sluicing? I was no Burke and wills here as the site has been know and detected for years, and easy to get to...just hung around went slow and after a few hours got lucky.....Mind was racing all the way home thinking who and what this guy had done..
